Mass flow meter range and measurement principle - focus on microfluidic control technology

The mass flow meter is the most accurate and the installation requirement of the medium in the existing industrial production. Because it can directly detect the quality, density and temperature of the medium flowing through the measuring tube inside the meter, there is no strict layer for the flow state of the medium. The flow requirement can be installed arbitrarily like a regulating valve, which greatly facilitates the construction and installation on site.
The main scope of use of mass flow meters:
It is mainly used to measure the mass flow rate and total amount and density of the medium. At the same time, it can also measure the volume flow rate and total amount, medium temperature, water content, alcohol alcohol content, concentration of two liquids with relatively uniform mixing, and process flow. The ratio of raw materials in the middle.
As for its application to the petroleum industry, such as crude oil production measurement, water content, single well production measurement, crude oil transportation measurement, chemical industry, food industry, pharmaceutical manufacturing industry, such as liquid pharmaceutical production measurement, paper industry, such as pulp measurement, textile Printing and dyeing industry, energy transmission measurement, such as liquefied gas metering, environmental protection industry, such as sewage treatment; desulfurization process to measure slurry density.
The flowmeter can play a very effective role in the batching and batch metering of various feeds, the metering and control of material flow during the process, the rapid and variable density measurement, and the quality monitoring of the product. ,

Measuring principle of mass flow meter:
1 mass flowmeter uses the thermal measurement to measure the flow rate by the molecular mass of the separated molecules. Because it is measured by the sensible heat, it will not affect the measurement result due to the change of gas temperature and pressure. . At the same time, it is also a relatively accurate, fast, reliable, efficient, stable and flexible flow measurement instrument, which will be more widely used in petroleum processing, chemical industry, etc. It is believed that it will show great potential in promoting flow measurement.
2 mass flowmeter can also measure the density of the medium and indirectly measure the temperature of the medium. Since the transmitter is a smart meter with the single chip as the core, more than ten parameters can be derived for the user according to the above three basic quantities. Because of its flexible configuration, powerful functions and high cost performance, this flow meter is a new generation flow meter.
3 With the improvement of automation level, many production processes have put forward new requirements for flow measurement. The chemical reaction process is controlled by the quality of the raw materials. The heating and cooling effects of the vapor and air streams are also proportional to the mass flow. Strict control of product quality, accurate costing, and fuel quantity control for aircraft and missiles also require precision. Therefore, the mass flow meter is an important flow measuring instrument.
